US Stocks Fall for Third Straight Session

The S&P 500 and Nasdaq-100 indexes fell Tuesday, marking the third consecutive trading session of declines for the major U.S. equity benchmarks [1, 2, 3].

This downturn reflects growing investor anxiety over the sustainability of artificial intelligence valuations and the impact of rising borrowing costs on growth stocks. As the market grapples with these pressures, the volatility highlights a shift in sentiment regarding the pace of AI-driven returns.

Market analysts identified two primary drivers for the slide. The 10-year Treasury yield reached its highest intraday level since early 2025 ^[2]. Higher yields typically make stocks less attractive compared to fixed-income assets, putting downward pressure on equity valuations across the board.

Simultaneously, the technology sector faced significant headwinds. Chip stocks dragged the broader indexes lower as investors braced for upcoming reports from Nvidia [2, 3]. This sector-specific pressure was compounded by concerns over AI-related earnings and the implications of recent Federal Reserve minutes ^[3].

Analysts on Bloomberg Television said that the combination of macroeconomic data and corporate expectations created a challenging environment for the Nasdaq-100. The index, which is heavily weighted toward technology firms, remained particularly sensitive to the fluctuations in Treasury yields and the anticipation of AI performance metrics ^[1].

While some reports emphasize the role of the Federal Reserve's minutes in triggering the sell-off, others point to the Treasury market as the primary catalyst [2, 3]. Despite these differing views on the lead driver, the result was a synchronized dip in both the S&P 500 and the Nasdaq-100 by the close of the market day on May 19 [1, 2].
